Answer:
10cm
Step-by-step explanation:
The formula for perimeter is:
Let the width of the rectangle be x then the length would be...
3+x
Now, let's plug these values into the equation and solve. (Note we are also given perimeter is 34 cm):
And since the length is x+3 then it is...
x+3=7+3=10cm
Answer:
Yes
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction. In this case, the fraction is being expressed by a decimal. So therefore 7.29 is a rational number.

Answer:
$623.64
Step-by-step explanation:
To determine the money she could have saved if she paid the furniture in full, you have to determine the total amount she will pay when she completes the 18 payments and subtract the price of the furniture from that:
Total amount= 267.98*18
Total amount=4,823.64
$4,823.64-$4,200= $623.64
She have saved $623.64 if she paid for the furniture in full.
By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.
<h3>How to derive the equation of the axis of symmetry </h3>
In this question we know the locations of two points with the same y-value, which means that the axis of symmetry is parallel to the y-axis and that both points are equidistant. Thus, the axis of symmetry passes through the midpoint of the line segment whose ends are those points.
First, calculate the coordinates of the midpoint by the midpoint formula:
M(x, y) = 0.5 · (- 7, 11) + 0.5 · (3, 11)
M(x, y) = (- 2, 11)
Second, look for the first coordinate of the midpoint and derive the equation of the line associated with the axis of symmetry:
x = - 2
By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.
